The most common simplified overview description of the B cell differentiation pathway involves the following steps: an antigen interacts with the corresponding surface membrane immunoglobulin after which the B cell begins expressing receptors for growth factors secreted by T cells (BCGFs and IL-2), after these factors bind, the lymphocytes ...
The process of immunological B-cell maturation involves transformation from an undifferentiated B cell to one that secretes antibodies with particular specificity. [1] This differentiation and activation of the B cell occurs most rapidly after exposure to antigen by antigen-presenting cells in the reticuloendothelial system, and under modulation by T cells, and is closely intertwined with ...
This cytokine is expressed in B cell lineage cells, and acts as a potent B cell activator. It has been also shown to play an important role in the proliferation and differentiation of B cells. [7] BAFF is a 285-amino acid long peptide glycoprotein which undergoes glycosylation at residue 124.
B cell activation: from immature B cell to plasma cell or memory B cell Basic B cell function: bind to an antigen, receive help from a cognate helper T cell, and differentiate into a plasma cell that secretes large numbers of antibodies. B cell activation occurs in the secondary lymphoid organs (SLOs), such as the spleen and lymph nodes. [1]
Specifically, cell differentiation in animals is highly dependent on biomolecular condensates of regulatory proteins and enhancer DNA sequences. Cellular differentiation is often controlled by cell signaling. Many of the signal molecules that convey information from cell to cell during the control of cellular differentiation are called growth ...
B-cells form in the bone marrow and undergo gene rearrangement in order to develop B-cell receptors (BCRs) that bind to a specific antigen. Once activated by an antigen, B-cells proliferate and further differentiate into plasma cells and memory B-cells. [4] B-cells that have not encountered an antigen are called naive B cells.
CD19 is widely expressed during all phases of B cell development until terminal differentiation into plasma cells. During B cell lymphopoiesis, CD19 surface expression starts during immunoglobulin (Ig) gene rearrangement, which coincides during B lineage commitment from hematopoietic stem cell. [8]
